Kernel Upgrade

Thursday, February 14. 2008
There was a pretty nasty bug discovered in the Linux kernel version I was using that allowed those with SSH access to create a program that escalated their privileges and allowed them to take control of the server. I've upgraded the kernel and resolved the issue successfully, with a very minimal amount of downtime.

Information regarding the exploit: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=464953

Downtime, etc.

Wednesday, July 25. 2007
Four days ago I performed a system upgrade from Debian Sarge to Debian Etch, providing more up-to-date and secure software for your consumption. This upgrade involved a system reboot for the kernel, and unfortunately I'm going to have to take it down for a little bit shortly.

To keep up with demands on my server I'm going to upgrade the available RAM in the system from 512MB to 1GB. I'm planning on having this executed on Friday the 27th at 17:00 GMT. This will give more room for the applications you all have requested to breathe and function more effectively. If you have any problems with this time, please let me know in a comment and I'll try to work around it.
